Unplug all USB attachments and restart your PC then again plug in your mouse and keyboard. Unplug your USB Mouse and then again plug it back after few minutes. Try using a different USB Port and see if it works. Check if other USB devices are working or not.

So, whilst your mouse is unresponsive, the keyboard is still somewhat usable, right? Try ctrl+alt+del combination to access Windows task manager/Security menu (shortcut will prompt you to shutdown PC/logout on Gnu/Linux OSs) and kill frozen application/s (you can move through the tabs using the TAB key, Menu key will bring up the context menu) or reboot the system if there's no unsaved project you're working on.
